I haven’t studied fish movement. But, the way that the fish I studied moved did play a big role in why I studied them. Anchovies are really efficient filter feeders. One of the ways that they feed is by opening up their mouths SUPER wide and just swimming – letting everything get caught in their net like gills. SOOO cool. Here’s a picture of an anchovy swimming with its mouth closed:
Here’s a picture of an anchovy swimming with its mouth open:
How cool is that???
When I was running my experiments, I would check to make sure that they were swimming open mouthed – if they weren’t I knew that they weren’t feeding and THAT was going to be a problem.

As a physicist, I don’t actually study fish. However, I’ve always found it amazing how large shoals of silvery fish all seem to move together as one – I’m sure there’s physics to be done in there somewhere!

Only fish I ever studied is zebrafish and it can move really fast! I’m telling you they are really agile when you are trying to catch them to pair them up! They also all used to come to the side of the tank inthe mornings when we entered the room because they new they were going to be fed, and then they say fish don’t have a good memory!!

Not one I’ve researched but the Blue Marlin is fascinating just for the sheer speeds it can reach in the water. Approaching 70mph, helped by a very hydrodynamic profile and obviously, the massive sword for a nose that literally cuts through the water!
